The mr William two questions please!

well, in short, the students and chaperones are at a 2 : 9 ratio, and we know there are 171 students, how many chaperones then, so long they maintain a 2:9 ratio?

$\bf \cfrac{chaperones}{students}\qquad 2:9\qquad \cfrac{2}{9}\qquad \qquad \cfrac{x}{171}=\cfrac{2}{9}\implies 9x=2(171) \\\\\\ 9x=342\implies x=\cfrac{342}{9}\implies x=38$

How to find the point slope form with the slope of 3 and the point of -2/6

Levart [38]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:y-6 = 3(x + 2)$

____________________________________

$\large \tt Solution \: :$

Equation of line in point - slope form :

$\qquad \tt \rightarrow \:y-y_1 = m(x - x_1)$

$\tt \:m = slope=3$

$\tt y_1 = y \: \: coordinate \: \: of \: \: point = 6$

$\tt \:x_1 = x \: \: coordinate \: \: of \: \: point = - 2$

Here :

$\qquad \tt \rightarrow \:y - 6 = 3(x - ( - 2))$

$\qquad \tt \rightarrow \:y - 6 = 3(x + 2)$
